Multilayer insulating panel for the installation of an electric heating system in subfloors or walls

Abstract

A multilayer insulating panel is for the installation of an electric heating system having electric heating wires in a subfloor or in a wall of a building. The panel includes a main insulating layer including a first surface and a second opposite surface. A sheet made of polymeric material is operatively associated with one of the first or second surfaces. The sheet has a first face and a second opposite face and includes reliefs equally spaced apart on the first face to fix the electric heating wires on the first face in a reversible manner. A connection layer is fixed to the second face of the sheet. The connection layer is interposed between the second face of the sheet and one of the first surface or the second surface of the main layer following the association of the main insulating layer with the polymeric sheet.

Description

BACKGROUND ART OF THE INVENTIONField of Application[0001]The present invention generally relates to heating systems of buildings, placed in subfloors or walls. In particular, the invention relates to a multilayer insulating panel which can be used for the installation of an electric heating system including electric heating wires, in the subfloors or walls of a building.Prior Art[0002]Floor or wall heating systems of buildings which employ piping or electric cables placed under the floor of the building or in the wall cavities for irradiating heat into the rooms, are known and commonly used.[0003]In particular, floor heating systems using water comprise coil piping in which heated water (or other fluids) flows, being generated by using a traditional boiler, a heat pump, a fireplace stove or by means of photovoltaic solar panels.[0004]Floor electric heating systems generally comprise electric cables operating as electrical resistance or electric heating wires which, if crossed by ele...

AI Technical Summary

Benefits of technology

The invention is a multilayer insulating panel that includes an embossed sheet that sticks better to the insulating layer. The panel is also made with less expensive manufacturing methods and uses alternative insulating materials to polystyrene. The panel has superior heat insulation and is thinner.

Problems solved by technology

Thereby, the gluing of the embossed sheet to the polystyrene sheet of the panel is not very effective.

The insulating panel as a whole may suffer from involuntary detachments of the embossed sheet, especially if the insulating panel is laid in the cavities of a wall for providing a wall heating system, that is on a plane orthogonal to the plane of the slab.

The thermoforming process employed is a batch process, which is generally complex and slower in terms of processing times as compared to other industrial manufacturing processes.
